POLY 103 |
| Combination of RAFT polymerization and click chemistry was studied to modify the surface of silica nanoparticles. Polystyrene (PS) grafted silica nanoparticles were prepared by a tandem process that simultaneously employs reversible addition fragmentation transfer (RAFT) polymerization and click chemistry. In a single pot procedure, azide-modified silica, an alkyne functionalized RAFT agent and styrene were combined to produce the desired product. The grafting density of PS on the silica in the tandem process was intermediate between analogous “grafting to” and “grafting from” techniques for preparing PS brushes on silica. Relative rates of RAFT polymerization and click reaction were altered to control grafting density. |
